KILLER, F CANTON, OHIO, ASSIGNOR TO THE ROLLER BEARING COMPANY, OF CANTON, OHIO, A CORPORATION OF OHIO BEARING ADJUSTING AND LOCKING DEVICE Application filed July 27,

bearing adjustin and locking device and in the parts and com inations and arrangements of partshereinafter described and claimed.

In the accompanying drawings, Fig. 1 is a longitudlnal sectional view of a shaft bearing and an adjusting and lockin device therefor embodying my invention. ig. 2 is a detail view of one of the two washers forming part of the device, being the washer that abuts against the bearing,

Fig. 3 is a detail view of the other wash-er, Fig. 4 is an edge view of said second washer, and

Fig. 5 is a detail. view of the locking pin. The drawings illustrate a shaft 1 on which is. mounted an antifriction bearing, the particular form of bearing illustrated in the drawings being a taper roller bearing com prising a cone or inner race-member 2, a cup or outer race member 3 and conical rollers 4 therebetween held in a conical cage 5. so Abutting against the end of the bearing cone 2 is an annular washer 6 having a notch 7 in its periphery. Spaced slightly from said washer 6 is a second or outer washer 8 that is provided with a notch 9 in its periphery that alines with the notch 7 of the inner washer. Notched shims 10 are interposed between the two washers.

The shaft 1 is provided with a cross bore 11 through which extends a locking pin 12, both ends of which engage the outer washer -8. Preferably the outer washer is provided with diametrically. spaced concave depressi2ons 13 adapted to receive the locking pin 1 j The .bearing is adjusted by placin the required number of shims 10 between t e. inner washer 6 and the outer washer 8=and then positioning and lockingthe outer washer by driving the locking pin 12 through the cross bore 11 of the shaft 1.

1929., Serial no. 881,585.

In order to prevent creeping of the washers or shims on t e shaft which would resulti'n wear of the shims, the locking pin 12 may be provided with a projecting dog 14 at one end that extends into the alined notches of the washers and shims. The locking pin may-be held in place by means of a cotter pin 15 at the end opposite said dog 14.

The above construction dispenses with the threaded adjusting and locking devices commonly used and it is simple in construction and comparatively inexpensive to make. By

preventing creeping and excessive wear of the shims, a great disadvantage of ordinary shim-adjusting devices is obviated. If deslred the locking'pin and the shaft bore and washer depressions may be tapered.

What I claim is:

1. A device for adjusting and locking antifriction bearings including a race member, comprising a washer for abutting against said race member, an outer washer spaced slightly therefrom, shims interposed between said washers, a locking device engaging said outer washer to hold the parts in position,

said locking device having a portion holding said shims and washers against rotation relative to each other.

2. A device for adjusting and locking antifriction bearings including a race member mounted on a shaft, comprising a washer for abutting against said race member, an outer washer spaced therefrom, shims inte osed between said washers and a locking pin extending through a transverse bore provided therefor in said shaft and engaging said outer washer, said washers and said shims having alining notches and saidlocking pin having a projecting dog extending into said notches.

3 A device for adjusting and locking anti friction bearings including a race member mounted on a shaft, comprlsing a washer for abut-ting against said race memb r an outer washer spaced therefrom, shims interposed. between said washers and a locking pin extending through a transverse bore provided therefor in said shaft and engaglng said outer washer, said outer washer having diametrically spaced concave depresslons adapted to receive said locking in saidi washers and said shims having almingnotches and said locking in having a. projecting dog extending into sald notches.
